Plasmids are unique to what?
Plasmids are unique to bacteria and other prokaryotic organisms. They are small, circular DNA molecules that can replicate independently from the host cell's chromosomal DNA. Plasmids often carry genes that provide the host with additional functions, such as antibiotic resistance or the ability to metabolize certain nutrients.
Are plasmids self-replicating?
Yes, plasmids are self-replicating circular DNA molecules that exist independent of the bacterial chromosome. They carry genes that provide advantages to the host organism and can replicate within the host cell.
What type of plasmid is the source of the problem with antibiotic resistance?
The source of antibiotic resistance is often plasmids known as R plasmids, which carry genes that confer resistance to antibiotics. These plasmids can be transferred between bacteria, spreading antibiotic resistance throughout microbial populations.
Do all microbes have plasmids?
No, not all microbes have plasmids. Plasmids are small, circular pieces of DNA that are separate from the microbial genome. While plasmids are common in many bacteria, they are not present in all microbes.
Give two reasons why a plasmid is useful for DNA transfer?
Plasmids are useful for DNA transfer because they are small, circular DNA molecules that can replicate independently from the host genome, making them easy to manipulate and transfer between different organisms. Additionally, plasmids can carry genes that confer selective advantages, such as antibiotic resistance, allowing for the creation of genetically modified organisms.
Do mitochondria have plasmids?
No, mitochondria do not have plasmids. Plasmids are small, circular DNA molecules often found in bacteria and other prokaryotic organisms, but not in eukaryotic organelles like mitochondria. Mitochondria have their own separate DNA that is usually in the form of a circular chromosome.
What cells have plasmids?
Plasmids are commonly found in bacterial cells. They can also sometimes be found in other single-celled organisms like yeast.

How is the artificial manipulation of plasmids used for technological applications?
Artificial manipulation of plasmids is used to introduce specific genes into organisms for various technological applications, such as producing pharmaceuticals, biofuels, and enzymes. This technique allows for the genetic modification of organisms to enhance their abilities to produce desired products. Additionally, plasmids can be engineered to carry genes that confer resistance to specific environmental stresses or pathogens, making them useful in bioremediation and as tools for studying gene function.
Do they prokaryotes or bacteria mean nucellus not nucleus?
They are non-nucleated organisms and have nuclear material in the form of dense DNA clusters or plasmids
Are plasmids self-replicating?
Yes, plasmids are self-replicating circular DNA molecules that exist independent of the bacterial chromosome. They carry genes that provide advantages to the host organism and can replicate within the host cell.
What type of plasmid is the source of the problem with antibiotic resistance?
The source of antibiotic resistance is often plasmids known as R plasmids, which carry genes that confer resistance to antibiotics. These plasmids can be transferred between bacteria, spreading antibiotic resistance throughout microbial populations.
What are the 2 types of DNA plasmids found in microorganisms?
The two types of DNA plasmids found in microorganisms are conjugative plasmids and non-conjugative plasmids. Conjugative plasmids are able to transfer genetic material between bacteria, while non-conjugative plasmids do not have this capability.
What is a promiscuous plasmids?
A promiscuous plasmid is a type of DNA molecule that can be transferred between different bacterial cells through processes such as conjugation, transformation, or transduction. These plasmids often carry genes that promote their own transfer and can spread rapidly among bacterial populations.
Plasmids are circular pieces of DNA that exist in addition to the chromosomal DNA of certain bacteria and yeast?
Plasmids often contain genes that give organisms various abilities, such as antibiotic resistance or the ability to metabolize certain compounds. They can be passed between bacteria through horizontal gene transfer, allowing for the rapid spread of these traits within a bacterial population. Plasmids are used extensively in biotechnology as vectors for introducing foreign genes into organisms for research or commercial purposes.
What are the degradative plasmids and what are their properties?
Degradative plasmids are a type of plasmid that carry genes encoding enzymes which allow the host bacteria to degrade or metabolize specific compounds, such as pollutants or toxins. These plasmids can confer a selective advantage to bacteria in environments with those compounds, as they provide the ability to break them down for energy or survival. Examples include plasmids carrying genes for the degradation of hydrocarbons or pesticides.
Is prokaryote used in plasmids?
No, it's vise versa. Plasmids are used in and by the prokaryotes.
